Manufacturers in R&D, designand quality control can monitor consistent package integrity with the latest addition to US-based Sensor Products range of tactile pressure-indicating sensor films.

Pressurex Zero® is a thin plastics film that is placed between any two contacting or mating surfaces to instantly measure and map pressure magnitude and distribution. Variations in contact surface pressure are visible by the impression made on the film, which instantaneously and permanently changes colour proportional to the actual pressure applied.
